5.9 magnum with M122 blower/intercooler
I opted to take the path I did so as to have the smallest belt surface area and tensioner force to minimize parasitic loss but without getting into belt slippage. Belt type is another factor in what you can get away with. No issues with belt slippage but if I ever see that I'll increase tensioner force. Mine is a 3 lobe model 112 with 3.4" & 5.375" pulley diameters (6 psi). The 6 rib pulley is what the Magnuson comes with. This is an older picture. I don't have any front-view pictures showing the support bracket and tensioner or belt to pulley path.
